Definitions

  • the invention relates to a door system for an elevator installation and an elevator installation with such a door system.
  • Elevator systems are usually arranged in an elevator shaft that connects several floors.
  • the elevator shaft has shaft door openings at the height of the individual floors.
  • Shaft doors are arranged at these shaft door openings.
  • the elevator system includes an elevator car, which is arranged to be movable within the elevator shaft.
  • the elevator car has a car door opening.
  • a car door is arranged at this car door opening.
  • Both the shaft doors and the at least one car door usually each have at least one door leaf.
  • EP 2 088 273 A1 shows an opening and closing mechanism for an elevator door designed as a folding door.
  • the elevator door comprises a door drive, a belt coupled to the door drive and a linkage connected to this belt.
  • the folding door includes a leading and a trailing door leaf.
  • the door drive comprises a motor and is coupled to the leading door leaf by means of the linkage in such a way that when the motor shaft rotates, the leading door leaf is pivoted out of its door-closing plane and the door is then opened. If the door leaves are arranged in their door-closing plane, the elevator door is considered to be locked due to the functionality of the linkage under the influence of the holding current of the motor.
  • the disadvantage is that the mechanism of such a door system is complicated and electrical energy is required to lock the door.
  • a door system for an elevator system includes a drive unit with a driven, pivoted shaft and a blocking element, wherein the blocking element is fixed to the shaft, at least one pivot unit, each of the at least one pivot unit comprising a pivot axis that can be coupled to a door leaf and a blocking recess, the blocking recess being fixed to the pivot axis, a pivot movement of the pivot axis being controlled by a first end position describing an end position of the door system is limited, the blocking element interacting with the blocking recess in such a way that the blocking element engages in the blocking recess and the pivot axis can thus be blocked in the first end position.
  • a first of the end positions corresponds to the open position of the door system, a second of these end positions corresponds to the closed position of the door system.
  • a door system of an elevator installation can include both a car door and a shaft door, which are spaced apart from one another in the closed position of the door system, preferably by means of a door sill gap.
  • the drive unit comprising the shaft can accordingly be part of the car door or the shaft door, with the pivot axis being able to be a part of the car door or the shaft door independently of this.
  • the invention is based on the development that the pivot axis which can be coupled to the door leaf and whose pivoting movement causes an opening or closing movement of the door leaf may be locked in at least one of its two end positions.
  • a pivoting movement is a rotating movement, in which case it is not possible to carry out a complete revolution in one direction of rotation.
  • the pivot axis has a maximum angle of rotation of less than 360° at any point in time within a period of time, which preferably includes an entire door opening and door closing process.
  • pivot axis cannot be pivoted or rotated through 360° or beyond during the door opening or door closing processes. Starting from a position of the pivot axis corresponding to the closed position of the door system, the pivot axis is therefore at none Time panned 360° or beyond.
  • the blocking element attached to the driven shaft of the door drive engages in the blocking recess attached to the pivot axis and thus prevents an undesired opening or closing movement of the door leaf, preferably by means of a form fit.
  • a form fit as mentioned in this description can be achieved, for example, in that the blocking element is formed by a circular section of a circular disk arranged perpendicularly to the shaft, the associated circle center point of this circular section being arranged on the axis of the shaft belonging to the door drive.
  • the locking recess fixed to the associated pivot axis has a circular section. In the end position of the pivot axis, this circular section is positively adjacent to the circular arc of the circular section belonging to the blocking element, so that when the shaft is in the open or closed position of the door system, a pivoting movement of the pivot axis is prevented.
  • a form fit as mentioned in this description can also be achieved, for example, by forming the blocking element from one or at least two pin(s) engaging in the blocking recess and thus preventing the pivoting movement of the pivot axis from the end position.
  • the blocking element and the blocking recess interacting with this blocking element are designed in such a way that blocking of the pivot axis provided with the blocking recess is prevented during the pivoting movement of the pivot axis out of the blocking recess.
  • the interaction of the shaft with the pivot axis means that no additional control arrangement is required which uses a signal to unblock or unlock the door leaf before the opening or closing movement of the door leaf is completed.
  • one of the at least one pivoting unit is designed as a primary pivoting unit, with the primary pivoting unit comprising a second locking recess fixed to the pivoting axis of the primary pivoting unit, with the pivoting movement of the pivoting axis belonging to the primary pivoting unit being controlled by a second end position describing an end position of the door system is limited and the blocking element acts on the second blocking recess fixed to the pivot axis of the primary pivot unit in such a way that the pivot axis of the primary pivot unit can be blocked in its second end position.
  • the door leaf of the pivoting door can be blocked both in its open and in its closed position. Accordingly, a further locking device is not necessary, which allows the door leaf to be locked in the open or closed position.
  • the door system can comprise a car door and a shaft door, with the car door and the shaft door being spaced apart from one another when the door system is in the closed position, preferably by means of a door sill gap, with a first of the doors comprising the car door and the shaft door comprising the drive unit and the primary pivoting unit.
  • a first of the doors comprising the car door and the shaft door comprising the drive unit and the primary pivoting unit.
  • the drive unit can include a first driver means and the primary pivoting unit can include a counter-element that can be actuated by the first driver means, with the first driver means being fixed to the shaft and the counter-element of the primary pivot unit to the pivot axis of the primary pivot unit in such a way that the driver means a Causes pivoting movement of the pivot axis and a pivoting movement of the door leaf can be effected. In this way there is a possibility that both locking and pivoting of the door leaf can be achieved by means of the shaft and the pivot axis.
  • a further development of the door system comprises a car door and a shaft door, with the car door and the shaft door being spaced apart from one another when the door system is in the closed position, preferably by means of a door sill gap, with one of the at least one pivoting unit being designed as a secondary pivoting unit, with one or the first of the doors comprising the car door and the shaft door comprises the drive unit and the second of the doors comprising the car door and the shaft door comprises the secondary pivoting unit, the on the locking element fixed to the shaft acts on the locking recess of the secondary pivoting unit in such a way that the pivoting axis of the secondary pivoting unit can be blocked in its end position corresponding to the open position of the door system.
  • the secondary swivel unit is the swivel unit that is not arranged on the drive side. If the drive unit is part of the car door, then such a “secondary pivoting unit” is part of the shaft door. As an alternative to this, such a “secondary pivoting unit” is part of the car door if the drive unit is part of the shaft door.
  • the second of the doors comprising the car door and the shaft door can comprise a gear unit, with the gear unit comprising a further locking element, with the locking element of the gear unit interacting with the locking recess of the secondary pivoting unit in such a way that the pivoting axis of the secondary pivoting unit is in its end position corresponding to the closed position of the door system is blockable.
  • the gear unit can include a counter-element that can be actuated by the first entrainment means, with the blocking element of the gear unit and the locking recess of the secondary pivoting unit being designed in such a way that a blocking of the pivot axis of the secondary pivot unit can be canceled by actuating the counter-element of the gear unit by the first entrainment means. In this way, it is possible to lock or unlock the door leaf coupled to the pivot axis of the secondary pivot unit. During a pivoting movement of the pivot axis belonging to the secondary pivot unit, the locking element of the gear unit is pivoted out of the locking recess of the secondary pivot unit.
  • the drive unit can comprise a second entrainment means and the secondary pivoting unit can comprise a further counter-element that can be actuated by the second entrainment means, with the second entrainment means being fixed to the shaft and the counter-element of the secondary pivoting unit to the pivot axis of the secondary pivoting unit in such a way that the second entrainment means can be rotated during a pivoting movement of the wave one causess a pivoting movement of the pivot axis of the secondary pivot unit and a pivoting movement of the door leaf that can be coupled to the pivot axis can be effected.
  • both the first and the second pivot axis ie the car door panel and the shaft door panel, to be pivoted when the driven shaft is pivoted.
  • first and second entrainment means and the counter-elements fixed to the pivot axes can be fixed to the shaft or to the pivot axes in such a way that the pivot movements of the pivot axes of the primary and secondary pivot units take place essentially at the same time when the door system is opened or closed. In this way, a simple coupling of the car door to the landing door is made possible during the opening and closing movement of the door system. Accordingly, an additional device for synchronizing the movement of the shaft and car door panels is not necessary.
  • At least one door leaf can be pivotably arranged on the pivot axis assigned to this door leaf. Accordingly, the driven shaft of the door drive acts directly on the pivot axis of the door leaf, after which additional mechanically acting coupling elements between the shaft and the pivot axis can be dispensed with.
  • a further development of the door system is designed as a folding door system.
  • Such a door system designed as a folding door system has the advantage that the door system requires little space in a direction perpendicular to the door closing plane.
  • the shaft and/or the at least one pivot axis can be arranged essentially vertically along the elevator shaft or vertically in the elevator shaft.
  • the vertical arrangement of the shaft or the at least one pivot axis in the elevator shaft has the advantage that a space-saving arrangement of the drive unit or pivot axis is made possible, since it can easily be stowed in the doorpost or in the immediate vicinity of the doorpost.
  • an output shaft of a motor of the drive unit and the driven, pivotably mounted shaft are arranged coaxially with one another.
  • Such a coaxial arrangement has the advantage that the number of mechanical components of the door system can be largely reduced. For example, no gear or the like is required between such an output shaft and the pivoted shaft.
